PATENT {oFFlcE-v ASSIGNOIt, BY MESNE ASSIGNMENTS,'TO Y CHICAGO GOVERNOR & MANUFACTURING CO'.,"OF CHICAGO, ILLINOIS; .a CORPORA TIQN F ILLINOIS Appneatinn 'mea April 1s,

. This invention has to do with governors ofV scribed in which the adjusting parts,.as well as the operating parts, are completely en- L closed, resulting in a mechanism which is airtight, water-tight, dust-tight and tamper-vy l proof. f Another important object of the -invention isto provide, insuch a governor, novel means L for .increasing the iexibility, sensitiveness and accuracy'of the mechanism under the' suction to which the same is .subjected in use.

Still another important object is to pro- '.vide,in such a governor, novel means for fanism.

While the foregoing statements are indica-y tive in a general way of the nature of the invention, other more specific objects andad vantageswill vbe apparent to those skilled .in

the art upon a full understanding of the construction, arrangement and operationvof the improved governor.

.2Q cilitating ready adjustment of the mecha- In order that the invention may be readily Y understood, two diiferent embodimentsof the Asame are presented herein, but it. will of course be appreciated that such forms are. in- `tended primarily for the purpose of illustration and that the invention is susceptible of 5 embodiment in other structurally modied forms coming equally within the scope ofthe appended claims.

the governor, with the cover plate removed. -The form of governor shown in Figs. 1 to 4 inclusive will irstpbe described. Thel governor-which isadapted to be installed inthe vaporized -fuel line 10 of the engine between 55 the carburetorj-ll'and the 'intake manifold- 12J-includes a body-13 which is adapted to- Abef clamped by bolts 14 between coupling i'anges 15 and 16 formed respectively'on the opposing portions of the carburetor and in. take manifold; The body 13 contains a vaporized fuel passage 17 in registerwith the line A 10. The passage 17 is preferably of rectangular cross section, except at its lower end 18, where it'is preferably of enlarged up-v wardly converging-circular cross section.

, A valve 19, which is of the same shape as the cross sectional area of thepassage 17is positioned in the upper portion of the pas-r sageand is attached by a screw 20 -to a shaft 21 which is rotatably journaled in the body ina position cross'wise ofth passage. -One end of theshait 21 projects from the body into the interior of a flat casing 22, which casing" is attached by screws 23 to the body, 75

gralY part ofthe same. y

The casing 22 is of generally rectangular yshape and is provided at its front with a removable `cover plate 24;A The edges of the 80 coverplate are sealed against the rim 25 of j the casi-ng by an interposed gasket 26 Awhich is vsecured to'the inside face of'the )cover plate, and the cover plate is heldin place by a screw 27 Awhich extends through a holekin the centerof the 'cover plate landengages wi'thih a lscrew-threaded bore in a stud 28 which is `attached to the back of the casing.

When the screw 27 is dra-wn uptight, the

deringthe casing water-tight, airy-tight and dusttight. After the. screw 25 has been drawn up tight,` it maybe maintained-in` that position by the insertion therethrough f a sealing wire v.29, which wire .may also be inserted through one endv of one of the-bolts 14,` thereby. preventing any unauthorized i. person from` tampering with the adjustment of the mechanism located within the casingjlflv in a generally T-shaped formation. 'Ihe spring 32 is anchored at its upper end to the casing by apin 36 over which it is hooked; the spring 33 is anchored at its lower end to the casing by a pin 37 over which it is hooked;V and the spring 34 is telescoped at one end over, and liXedly secured to, a sleeve 20. 38 which terminatesbeyond the end of the spring in an enlarged nut formation 39. The nut 39 is screwed onto a threaded link 40 which terminates in an eye 41, and the eye 41 is detachably hooked over a pin 42 on the lower end of thearm 30.

The suction in the vaporized fuel passage 17 causedl by the operation of the engine acts upon the valve` 19, tending-to close the latter against the resistance'of the springs 32,

33 and 34.A As the speed of .the engine approaches the predetermined maximum speed for which the governor mechanism has been set, the valve 19 will move against the yielding resistance of the springs toward its closed position. `It is desirable that the initial movement of the valve toward its closed pov sition meet with but little resistance, since in the fully open position of the valve evena strong suction has but -very little-effect on the saine. But as the valve continues to close,

and is acted upon more strongly by the consequently increased` suction past the edge. thereof, 't is desirable that the springs af' ford al progressively increasing amount of resistance to the closing movement. The plural spring arrangement shown herein, illustrated and described, is-ideally suited for this purpose. When the valve 19 'starts to close, only the spring'32-which is has been produced,

Adjustment of comparatively weak-will resist-the closing movement. As the closing progresses, the

spring 33 will cme into play, and, after the Y.shaped spring formation shown in Fig. 3

spring 34 will proceed toyield, givinga very flexible, highly sensitive andl accurately compensating action. i

the governor -to` increase or decrease the maximum speed setting may .be accomplished ver;1 easily. -It is merely necessary to remove the outer cover plate 24,

-' unliook the `eye`411 of the adjustable turnbuckle arrangemen-tfromthe vpin 42, and rotate the link v40 one orA two turns into or out of the nut 39, or whatever amount is necessary orpre-scribed tov give the desiredspeed invention,

fuel passage,

the relatively strong able soprings pivotally setting. After the adjustment has been made, the eye 41 is hooked back onto the pin 42 again and the cover plate 24 is replaced. Since all of the working and adjusting parts of the mechanism are totally enclosed within the casing 22 behind the sealed cover late 24, the mechanism is rendered watertight, dust-tight, air-tight and tamper-proof. By having the mechanism air-tight, there is no danger of air being sucked into the casing and passing through the body along the shaft 21 into the passage 17, which seepage, if permitted, would interfere with the accuracy of the operation -of the mechanism.

In Fig. 5 is shown a modification of the invention in which only two springs 43 and 44-corresponding to the springs 32 and vided at its lower end with a laterally opening notch 50 which interfits laterally with the groove 47in the nut. In this -form ofthe as in the other form, one of the springs, and preferably the spring 43, yields before the other. Adjustment of the spring resistances may be easily effected by moving the nut 46 laterally out of the notch 50 and turning the nut in one on the link 45.

I claim:
